Abstract	The static problem of loading the eyeball by a thin cylindrical cornea-deforming rod is solved for obtaining data on the mechanical properties of the eye in clinical examination. The analysis is carried out within the framework of a simple model which treats the cornea as a soft shell and takes into account the elastic properties of the sclera and tissues surrounding it by introducing an elastic constraint between the intraocular pressure and the scleral part of the intraocular volume. The dependence of the intraocular volume on the pressure and the load applied, as well as on the elastic characteristics of the system, is investigated. The problem of relationship between the intraocular pressure and the load at a constant volume is considered. It is shown that loading the same eye by thin rods and flat stamps of different weights makes it possible to find in clinical examination the individual elastic characteristics of the eyeball and the pressure in the unloaded eye.
